In recent years, glass curtain walls have risen rapidly in our
country, and the glass curtain wall has the advantages of whole
body, light structure, elastic connection, shock resistance, easy
construction and convenient maintenance. At present, the glass
curtain wall in our country mainly has the frame, the
semi-concealed frame, the hidden frame and the whole glass curtain
wall, etc. Hidden frame aluminum alloy glass curtain wall, which
refers to the aluminum alloy in glass curtain wall, the appearance
is all glass, because of its unique whole mirror effect, and
favored by architects, are widespread used in more, high-rise
building

Selection of materials

Hidden box is mainly used in the aluminum alloy glass curtain wall
material of aluminum alloy profiles, glass and sealant three parts,
the material according to the local climate condition, both
beautiful and practical, durable and other factors, the current
employees.

Aluminium alloy section

The aluminum alloy profiles mainly guarantee the mechanical
properties of the curtain wall, i.e. strength (bearing capacity),
stiffness and stability requirements, while also satisfying the
requirements of aesthetics and durability. At present, the domestic
selection of aluminum alloy profiles, use the type curtain wall
series, such as 120 ~ 210 series profiles to choose, can be divided
into vertical and horizontal material, fixed pieces, such as
opening and closing, auxiliary parts.

Durability of aluminum alloy profile

The main consideration of aluminium alloy profile anodic oxide film
is not only decorative, but more important is to prevent the
harmful nature factors effect on corrosion of aluminum alloy,
thickness of oxide film shoulds not be too thin, not too thick, too
thick on the one hand, increase the cost of aluminum alloy anodic
oxidation, the other party possible oxide film and aluminum alloy
cohesive force is reduced, the oxide film layer is empty drum,
cracking and even falls off phenomenon. According to the inspection
standard of aluminum alloy construction profile (GB/t52337-93), the
thickness of oxide film should meet the requirements.
